[Libguestfs] virt-builder is very slow in git master when building ubuntu 14.04 vm
Hi All,
I been using virt-builder to create testing VMs (most ubuntu) for a
while, and it works great. But when I cloned the git repo today and
found the process becoming extremely slow, please see the output
below.
log that produced by pre-installed vendor package:

Turning on debug shows that it spent most of time spinning here:

[...]
Any idea what's the problem or is it a known issue ? Thanks.
